MAINTENANCE & ADJUSTMENTS
Safe Servicing Practices
Refer to the Safety Precautions section of this manual for
more service safety information.
Service Introduction
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis. For more detailed information order the correct
Parts
Manual and General Service Manual for your unit. Refer to the
Product Literature section of this manual.
Remain alert for unusual noises, which could signal a
problem. Visually inspect the machine for any abnormal wear
or damage. A good time to detect potential problems is while
performing scheduled maintenance service. Correcting the
problem as quickly as possible is the best insurance.
Clear away heavy build-up of grease, oil and dirt, especially
in the engine and under the seat platform areas; minute dust
particle are abrasive to close-tolerance engine and hydraulic
assemblies.
Inspect mower daily for grass clippings and wire or string
tangles. The underside of the mower deck will collect a build-
up of grass clippings and dirt, especially when grass is wet or
has high moisture content. This build-up will harden,
restricting blade and air movement and will probably show a
poorer quality of cutting. Therefore it should be removed
routinely.
To do this it will be necessary to raise and block the deck
using jack stands or blocks in the full up position. Scrape the
build-up from underneath.
IMPORTANT: Seat arm rests – Place the steering control
levers in the park brake position and pivot the arm rests
upward before lifting the seat platform to prevent arm rest
damage.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your BigDog

may raise the front of the mower
approximately 1" when first installed. It is not necessary to
re-level the deck at this time. Drive the mower for
approximately 20 minutes, stop the mower and check to see
if the deck is level. If adjustment is required, refer to the
mower’s General Service Manual for deck leveling
procedures.
Particular attention must be given to tightening
the drive wheel lug nuts and blade spindle bolts.
Failure to correctly torque these items may result
in the loss of a wheel or blade, which can cause
serious damage or personal injury.
Never attempt to make any adjustments to the
mower deck while the engine is running or with the
deck drive clutch engaged. Mower blades cannot
be seen and are located very close to the deck
housing. Fingers and toes can be cut off instantly.
